Towing with 4 Cyl

I personally wouldn't.  You will beat up the transmission, brakes and other on your Tucson.  Especially if it is newer and not a third car.  If it is something you don't mind beating up too much, then a little different.  1000lb towing limit is an extremely light tow rating.  That means that they built the vehicle with no intentions at all of towing.  Your boat, trailer and motor might not weigh that much, but your added gear likely has you at the limit.  Check out your gross vehicle weight rating as well, if you would consider putting all gear in your car and pulling the boat.  If you are moving it from a dry dock space to a launch that is 1/4 mile away or less, you could probably do.  I personally wouldn't do anything beyond that.  Especially with the cost of fixing issues that it could cause or having to replace a vehicle in the current market.
 
I used to do the same with my wife on the tow vehicle.  She couldn't even drive my car at the time (manual transmission), so kind of stuck her without a vehicle...  That didn't last long and I bought something that was able to tow.  If she can drive the Tuscon while you are fishing, it is probably best.

I think a rear drive 4-cyl vehicle would probably be ok, bu not the fwd Tuscon.  I had an old rear drive 4-cyl minivan that was an excellent tow vehicle.

I appreciate everyones input.  Might bite the bullet and think about shoppiing for a slightly beefier suv/truck once (if) this crazy vehicle maket improves.  

I personally use a 4 Cyl AWD Chevy Equinox to tow my 18ft Lund Alaskan. Its an older one being an 89 so its on the lighter side only weighting in at 436lb(Lund 89 catalog weight). Given trailer weight (single axle), just a rough guess but probably another 300-400lbs(could be wrong). At the ramp I put my emergency brake on when unloading so I don't rip my transmission apart shifting gears out of park to drive. Just my two cents, it would be nicer to have a v6 I feel though.

When I worked in the boat business many, many years ago, this was a very frequently asked question.

The answer was so much “can your vehicle tow the boat, but, more importantly, can your vehicle stop towing the boat, particularly in a panic or emergency situation.”

I would have no qualms about towing a boat that small with the Tucson. Doesn't matter if 4WD, FWD, or AWD. The motor is most likely a 2.4L or better, unless turbocharged, where it may be smaller. The 2.4L will do a fine job. The only thing about todays vehicles are the transmissions what with 8, 9, and 10 speed automatics, but if equipped with a 6 speed, and being a Hyundai, it's likely a tranny made by Aisin, and is a very good unit. The vehicles stock brakes should be more than adequate to stop under normal conditions. If you help the vehicle out when descending or pulling steep hills by manually downshifting then upshifting the trans, you should be fine for the life of the vehicle. Manual downshifting doesn't hurt anything 'cause electronic controls won't let it slam into a lower gear if going too fast. Additionally, it's not like you're draggin' that trailer everywhere you go. 
 
BTW, vehicles like the Equinox, Forester, Jeep Cherokee, etc. are primarily front wheel drive vehicles with an automatic coupling clutch for the rear differential. In bad road conditions when wheels might spin, you probably will never notice that the rear diff came in and then went back out. Control modules are reading the ABS sensors to determine wheel slip. If it's a little older vehicle like the Jeep Compass or Patriot, it may be equipped with a 4WD switch which, when engaged, simply locks the rear clutch in.
 
Tight lines!

My buddy (Spoon Chucker) would tow his (think) 21' bayliner fiberglass with the little Toyota tacoma. I was surprised how well that little bugger did and it surprisingly stopped good. Hed also haul loads of metal for me with it. I was a fan of those, but, atleast his was a little beast.
 
As someone else said, sometimes going isn't the problem, stopping is. Kind of like driving in the winter, if u can go, can u stop. Dad had a couple people at his shop always needing brakes and wouldn't listen to the reason.
 
Another thing is suspension. Need something decent so u don't get that woop dee woop feeling. In most cases a set of air shocks will help.
